A caller told police that Cruz had pulled the gun out and pointed it a passer-by near the intersection, according to preliminary information from a police report.

A San Antonio police officer responding to the call drove slowly behind Cruz and honked his horn to get Cruz’s attention, police said.

Investigators said Cruz initially looked over his shoulder at the officer’s vehicle. Cruz then turned around, pulled a handgun from his pants and fired at the officer, who returned fire, the report states.
